The Delta variant- first identified in India, is highly infectious and fast-spreading and was responsible for the second Covid-19 wave in the country, according to a government study. According to the study of INSACOG and NCDC, the Delta (B.1.617.2) variant has 50% higher transmission rate than Alpha (B.1.17) and the risk of breakthrough infections post Covid-19 vaccination is also high. But the scientists found no evidence of the role of the Delta variant in more deaths or the severity of cases not proved.
According to the study, the Delta variant presents in all states but has infected most in Delhi, Andhra Pradesh, Gujarat, Maharashtra, Odisha and Telangana, the worst hit in the second surge. Meanwhile, the UK's Public Health England (PHE) said that early evidence suggests there may be an increased risk of hospitalisation with the Delta variant compared to the Alpha but adds that more data is needed. With this variant now dominant across the UK. It remains vital that we all continue to exercise as much caution as possible."
Despite the coronavirus vaccination, the risk of infection with the B.1.617.2 variant remains high. As far as, the risk after vaccination from the alpha variant coronavirus is negligible. Because such a case has not been reported so far. In total 29,000 genome sequencing, more than 1000 cases of delta variant were reported. According to the Union Health Ministry, the cases of coronavirus infection in the country continue to decrease gradually. In the last 24 hours, 1,32,364 new cases reported and 2713 people have died.
